OK, there is a school of thought that if you alone use a device, whatever it may be, it will last for years, but if use is shared it will more likely go wrong. I have not done mega studies on this, but when I worked at a tv factory in the 1960s We often used test regs to test the assembled circuit boards. The cables would last for ever if I was using it, however two weeks holiday, and somebody ellse used it, the minute I started back wires would go intermittent or switches fail etc. It seems like the bending slightly differently or the different pressure on switches made it unreliable. I sold a TV once to a woman which had been working for several years. About three weeks after I sold it, the on off switch failed. It was just a simple mechanical push push latching switch. I had to pay half the repair costs, but why did it fail?
These sort of things are nothing to do with things having a mind of their own, they are purely down to the pattern or method of using a device. Brian
